Some Remarks on Fuzzy sb-Metric Spaces
, 2020 Fuzzy strong b-metrics called here by fuzzy sb-metrics, were introduced recently as a fuzzy version of strong b-metrics. It was shown that open balls in fuzzy sb-metric spaces are open in the induced topology (as different from the case of fuzzy b-metric

On best approximation in fuzzy metric spaces [PDF]
, 2015 summary:In this paper we introduce the notation of t-best approximatively compact sets, t-best approximation points, t-proximinal sets, t-boundedly compact sets and t-best proximity pair in fuzzy metric spaces.

A characterisation of completeness of b-fuzzy metric spaces and nonlinear contractions
Applicable Analysis and Discrete Mathematics, 2021 The purpose of this paper is to present a common fixed point theorem for a pair of R-weakly commuting mappings defined on b-fuzzy metric spaces satisfying nonlinear contractive conditions of Boyd-Wong type, obtained in D. W. Boyd, J. S. W. Wong: On nonlinear contractions, Proc. Amer. Math. Soc. 20 (1969), 458-464.

A Fuzzy Ranking Collaborative Multi-Tasks Data Collection Scheme in Ubiquitous Environments
IEEE AccessIn Ubiquitous Computing (UC) and the Internet of Things (IoTs), numerous devices collect and transmit data for sensing and control. However, connecting these devices effectively to foster collaboration is crucial for optimizing system performance.

The Hausdorff fuzzy quasi-metric [PDF]
, 2010 Removing the condition of symmetry in the notion of a fuzzy (pseudo)metric, in Kramosil and Michalek's sense, one has the notion of a fuzzy quasi-(pseudo-)metric. Then for each fuzzy quasi-pseudo-metric on a set X we construct a fuzzy quasi-pseudo-metric

Suzuki type fuzzy $\mathcal {Z}$-contractive mappings and fixed points in fuzzy metric spaces
, 2021 summary:In this paper, we propose the concept of Suzuki type fuzzy $\mathcal{Z}$-contractive mappings, which is a generalization of Fuzzy $\mathcal{Z}$-contractive mappings initiated in the article [S. Shukla, D. Gopal, W.

Some Remarks on Fuzzy N-Normed Spaces [PDF]
, 2009 It is shown that every fuzzy n-normed space naturally induces a locally convex topology, and that every finite dimensional fuzzy n-normed space is ...

Filomat, 2015 In this note we show a fixed point theorem for multivalued Caristi's type mappings on a large class of complete fuzzy metric spaces. In fact, this result allows us to characterize complete fuzzy metric spaces with continuous t-norm greater than or equal to the Lukasiewicz t-norm.
